R40 Diesel Destin's Exclusive Diesel Mechanic Shop

When you do business with R40 Diesel you can be sure you are in good hands.

Hey everyone! Here at R40 Diesel, we aren't just a diesel mechanic shop anymore! We are working on expanding into bigger and better things, such as wheels, tires, and tuners (programmers). We are expecting to keep evolving, with getting the word out by using our Facebook Page, as well as by word of mouth! Why go to a regular mechanic shop when you have a diesel, when you can come to the one place where you know you will be taken care of, the right way? Not only do we treat you right here at R40, but we also make sure that we take care of you, the customer, and your diesel. The mechanics here at the shop are very few in this area that are actually specialized in diesel trucks! We are looking forward to this new expansion, as well as acquiring new customers! We are also thrilled to take on new jobs, so if you are having any issues with your diesel or would like to upgrade it a little, please feel free to give us a call at the number below, or come on down and see us here at the shop!

We are also very excited and proud to announce that we are now Authorized Dealers for the following companies:

Sinister Diesel

American Force Wheels

FASS Diesel Fuel Systems

Bulletproof Diesel

Rough Country

PureFlow AirDog
